is the '09 sedan getting the new iDrive and the updated rear lights from September '08 production or is it phased in??? I talked to dealer today and he was not sure but did verify in the system that space grey is now available (which i know is old news but i wanted to test him to ensure he accessed the system)....I may get a late September production and wanted to see if worth the wait...also does anyone know if DCT software patch is updated in the '09 or a phase-in as well.....thanks
